The present invention relates to a stopping device for containerslike bottles and the like, apt to permit the gradual emptying olf of the container but not the introduction of a new liquid into said container. This device is ofthe type in which a shutting oi valve, movable inside of a cap xed to the neck of the bottle, and lockable, by operating a shutting cover external to the cap, onto a seat also fixed to the neck of the bottle, does not open if unlocked, but when the bottle has been inclined downwards vof an angle permitting the delivery, but not the introduction, of liquid. The device, according to the invention, shows a particularly original and ad'- vantageous structure, apt to ensure, through a very simple and easy operation, a regular working not subject to jamming caused, for instance, by sugary deposits or other similar drawbacks that happen with the known types.

Said device is characterised by this, that the i,

body of the valve has on its face opposed to the one turned towards the seat, a conical projection Whose axis coincides with that of the valve, and is apt to engage itself, for guiding the valve, into a corresponding cavity in a pin of the cover, mounted in an unseparatable, but rotatable and slidable way, in a hub integral to the cap, an additional guiding of the valve being ensured by a stem of the valve itself axially projecting from its face facing the seat through a ring centrally carried by said seat.

According to another characteristic of the invention the connection between pin and hub is fof the bayonet type so as to accelerate the operation of opening and closing the cover and correspondingly of the locking and unlocking of the valve body, which is provided, all around the conical projection, with a teeth formation with vwhich at rst engages the element of the bayonet joint fixed to the hollow pin, in order to impress to the valve a slight rotational movement and to loosen it from the seat to which it might eventually have stuck.

According to a further characteristic of the invention, the valve stem may carry at its free end a iioat which has the purpose, when necessary, of anticipating the beginning of the delivery of the liquid in respect with the angle of inclination of the bottle. n

Further particulars and characteristics of the object of the invention will be made evident by the following description of an example of construction, illustrated in the appended drawings, in which: n

Fig. 1 is for one half a longitudinal section of 2 the stopping device 'mounted on a bottle in a position of locked closure of the valve and for'the other half an elevational view of said device.

Fig. 2 is a longitudinal section of the device, with the bottle in a horizontal position and with the valve unlocked, but still in a closed position.

Fig. 3 is a longitudinal section of the device, with bottle inclined so as to provoke the opening of the valve for the delivery of the liquid.

Fig. 4 is an elevational view of the detail of the bayonet type connection for locking the cover of the cap and of the valve.

Fig. 5 is a partial plan view of the valve seat.

Fig. 6 is a section on line -y of Fig. 1 and Fig. '7 is a plan view of the device, one half Yof it with the cover of the cap in place and the other half without said cover. Y

On the mouth of the bottle I are applied, with the interposition of awasher gasket 2, plate 3 acting as a seat to the valve and cap 4, which are held fast in place by a collar 5 fastened to the neck o-f the bottle. On seat 3 ci the valve is indicated with 6 the delivery opening of the liquid at the center of which is disposed a ring 'I having a central hole I fast to the seat. Valve 8, located inside cap 4 is concave in shape and from its side facing the outside axially projects a conical 'part 9, whilst from the opposite end sticks out a stem I I) going through ring 'I of seat 3, and that in the examplev of the drawing is provided at its end with a float I I.

Said float is shaped like a double cone, with a taper corresponding to that of conical projection 9. Cap 4 is closed with the interposition of .a gasket ring I2, by a cover I3, on the internal face of which is ixed a hollow pin I4. Said pin I4 is.

unseparatably fixed, but is free to turn and slide, in a hub I5 of cap 4', whose flange connection to the cap has openings I6 for the delivery of the liquid and its lower end is so shaped, internally, as to consent the adaptation thereto vof projection 9 of valve 8, which rests with its conical surface against a corresponding conical surface of the lower end of hollow pin I4.

Around projection 9 Valve 8 is provided with a crown of teeth I'I, into two diametrically opposed spaces of which engage, when cover I3 is closed, the ends of two diametrically opposed teeth I8 of pin I4, the other ends of which find a rest on the lower annular surface of hub I5 forming two helicoidal paths. So, in order to open cover I3 it is suiiicient to cause it to turn so as to make teeth I8 slide over said helicoidal paths that end in axial blind grooves I9 of hub I5 diametrically opposed, into which teeth I3 are caused to penetrate, thus permitting of getting cover I3 away from valve 8 and to free the latter. Under these conditions valve 8 can slide on its seat 3, when bottle I (Fig. 2) is caused to be inclined, and displace itself axially keeping parallel with. its. axis to` the axis of. the bottle when the-inclination of the bottle is carried under a horizontal plane (Fig. 3) by means of the double guide provided by the engagement of projection 9 with the cavity of pin Hlf and offloat Il with ring l'. Only thenthe liquidcontained in the bottle can flow out. Cover Shas its peripheral edge knurled in order that it may be rotated easily and under the knurledA part 20 of the edge it has a tongue 2| soldered onto cap 4 so that cover and cap are astenedftogether when; after lling the bottle, the stopping. device described is applied thereon. On the upper' part of said tongue, between it and the cap, a small` passage may be left fora wire 22 permitting the application of a guarantee seal.v Said tongue is oi. very little strength and may very easily be broken by rotating cover I3- irl-respect with the capfwhenbeginning to use the bottle. The workingk of the device appears clearlyY from the drawingas it has beenexplained.

Asf-` may beV gathered` from the drawings, the valve ii-,has a recess. 8 facing the seats. Therefore, ifa person should intend` to refill the bottle lx in an unauthorized manner when theA bottle is in thetilted positionv shown in Fig. 3, the valve 8 would float on the liquid poured into the stopping device and vwouldk automatically engage its seat 3. Thus, the fbottle is automatically sealedand an unauthorized reiillingk of the bottle is rendered impossible.

It is understood that the constructional de` tails may be varied' within very wide limits in comparison withV those represented in the drawings; and*l abovedescribed, the. deviceA still remaining at all times Within the scope of the invention.
